Production introduction
Formulated in 3% and 6% concentrate ratios, AR-Afff Foam For Fire Fighting adapts to diverse system requirements: 3% for high-pressure setups, 6% for low-flow applications. Both variants feature a clear to pale yellow appearance and a pH of 7.8–8.6, minimizing corrosion risk in metal firefighting equipment. Key metrics include a surface tension of 15.5–17.0 mN/m (enabling rapid spread) and an expansion ratio of 6.8±1, producing dense foam that adheres to vertical surfaces.
Its alcohol-resistant core makes AR-Afff Foam For Fire Fighting indispensable in chemical plants, pharmaceutical facilities, and ethanol storage yards. The foam remains stable in temperatures from -15°C to 45°C, maintaining efficacy in cold warehouses or hot industrial zones. When diluted with water, it forms a dual-action film: smothering flames by blocking oxygen and cooling the fuel surface to prevent re-ignition.
Storage requires sealed containers in dry, ventilated areas, with a shelf life of 10 years under optimal conditions. Regular testing-via foam expansion and drainage checks-ensures AR-Afff Foam For Fire Fighting retains its alcohol-resistant properties. For teams facing polar solvent fires, this foam stands as a critical

Products Description
FAQ
Q: How does AR-Afff Foam For Fire Fighting differ from standard AFFF in terms of application speed?
A: It acts slightly slower than standard AFFF due to its thicker polymer structure, but forms a more persistent barrier. For fast-spreading fires, pair it with high-flow nozzles to accelerate coverage without compromising alcohol resistance.
Q: Can this foam be used in marine firefighting scenarios?
A: Yes, but rinse equipment thoroughly after use. Saltwater does not degrade its properties, but residual salt can clog nozzles-flush systems with freshwater post-deployment to maintain AR-Afff Foam For Fire Fighting compatibility.
Q: What dilution ratio is recommended for small-scale handheld extinguishers?
A: Use the 6% concentrate for handheld units, diluted with 94% water. This ratio balances foam density and portability, ensuring effective suppression in confined spaces like laboratory spills.
Q: Does AR-Afff Foam For Fire Fighting require specialized training to handle safely?
A: Basic foam handling training suffices, but teams should practice dilution ratio checks and foam quality tests. Avoid skin contact with concentrates-use gloves, as polymers may cause mild irritation.
Q: How does the foam perform in high-humidity environments?
A: Humidity does not affect its efficacy, but store concentrates away from moisture to prevent caking. Once diluted, the foam remains stable in humid conditions, making it suitable for tropical industrial facilities.
